The third order elastic constants of aluminum
The complete set of six third order elastic constants of single crystal A1 has been experimentally determined by measuring both hydrostatic pressure and uniaxial stress derivatives of the natural sound velocities using a two specimen interferometric technique. The values obtained are ...in units of …

The second and third order elastic constants of magnesium
The complete set of the ten third order elastic constants of magnesium has been determined experimentally from measurements of the hydrostatic pressure and uniaxial compression derivatives of the natural sound velocities using an ultrasonic pulse superposition technique. The specimen was neutron …

Long-range forces in sodium chloride
The third order elastic constants C144 and C166 of NaCl have been determined more accurately than heretofore. The results are C144 = .185 ± .015 and C166 = -.635 ± .015 in units of 10 12 dynes/cm2. The NaCl structure provides one with a unique opportunity for the measurement of long range forces in …

BODY TENSOR FORMALISM IN FINITE DEFORMATION ELASTICITY AND APPLICATION TO THE TORSION OF A CIRCULAR CYLINDER
… body tensor formalism for homogenous, isotropic elastic materials. This formalism is general and not limited to small deformations. One examines the physical laws and the constitutive equation which relates the stress to the strain with the help of the two Lame coefficients and the three third …

Characterization of nonlinearity parameters in an elastic material with quadratic nonlinearity with a complex wave field
This research investigates wave propagation in an elastic half-space with a quadratic nonlinearity in its stress-strain relationship. Different boundary conditions on the surface are considered that result in both one- and two-dimensional wave propagation problems. The goal of the research is to …

Analysis and development of particle based heat transport models for use in nanoscale structures.
… one of the main issues which must be overcome in order to maintain the continued reduction of feature sizes in silicon microelectronics. The new materials and device architectures which are used to achieve better performance have had a detrimental effect on thermal management due to higher thermal …
